Questions 21 to 25 are based on the following passage:
Joblessness is far more than an economic misfortune.It can be a
psychological disaster for the unemployed and their families.It can
cause illness,divide families and create a downward spiral of
feelings of worthlessness and lack of self esteem.According to
research done by M. Harvery Brenner,associate professor of health at
Johns Hopkins University,every 1% increase in the unemployment rate
translates into 37,000 deaths over the next 6 years,including over
20,000 deaths from heart attcks,900 suicides and nearly 500 deaths
from cirrhosis of the liver.In addition,Brenner estimates that 7,500
unemployed or their families will be admitted to prison after
committing a crime or to a mental hospital.
“The impact goes well beyond the individual who loses a
job,”said Brenner.“stress caused by economic factors affects our
national life at every level.”Men who have been socialized as the
family breadwinner are especially hard hit by unemployment.They
suffer greater depression and anxiety and have a higher possibility
of psychotic behavior than men who are employed.
“Nine months seems to be a crucial point when hope and patience
give out,”said a leading psychologist. After
that,“illness,suicide,alcoholism,divorce,and even crime grow at
epidemic rate.”Left without a job,many workers feel they have
nothing to look forward to.They miss their co�workers and the
routine of going to work.For many,the sense of hopelessness grows
worse every time they are rejected for a new job.When this happens
often enough,the rejection unemployed workers feel may be exacerbated
if some friends and neighbors avoid them as if they had a contagious
disease.

（英语）英语阅读理解练习题20篇及解析一、高中英语阅读理解1．阅读理解Many people have long dreamed of being able to fly around as simply as riding a bicycle. Yet the safety and strength of a flying bike was always a big problem. Over the past 10 years, developments in technology have moved the dream of personal flying vehicles closer to reality. Now, two groups of inventors say such vehicles may be available soon.The British company Malloy Aeronautics has developed a prototype (原型) of its flying bicycle. Grant Stapleton, marketing sales director of Malloy Aeronautics, says the Hoverbike is able to get in and out of small spaces very quickly. It can be moved across continents very quickly because it can be folded and packed, he adds.Mr. Stapleton says safety was the company's main concern. He says the designers solved the safety issue by using overlapping rotors ( 交叠式旋翼 )to power the vehicle.The company is testing a full-size prototype of the Hoverbike, which will most likely be used first by the police and emergency rescue teams.In New Zealand, the Martin Aircraft Company is also testing a full-size prototype of its personal flying device, called the Jetpack. It can fly for more than 30 minutes, up to 1,000 meters high and reach a speed of 74 kilometers per hour.Peter Coker is the CEO of Martin Aircraft Company. He said the Jetpack “is built around safety from the start. In his words, reliability is the most important element of it. We have safety built into the actual structure itself, very similar to a Formula One racing car.”The Jetpack uses a gasoline-powered engine that produces two powerful jet streams. Mr. Coker says it also has a parachute (降落伞) that can be used should there be an emergency. “It starts to work at very low altitude and actually saves both the aircraft and the pilot,” he adds. Mr. Coker says the Jetpack will be ready for sale soon.（1）We can learn from the passage that the Hoverbike .A. can hardly get in and out of small spaces quicklyB. can fly for over 30 minutes, up to 1,000 meters highC. has been used by the police and emergency rescue teamsD. can be transported quickly after being folded and packed（2）The writer uses the example of For One racing car to show that .A. the Jetpack is very safe and reliableB. the engine of the Jetpack is powerfulC. the actual structure of the Jetpack is uniqueD. the Jetpack can reach a great speed and height（3）The underlined word “it” in the last paragraph refer s to.A. the jet streamB. the engineC. the JetpackD. the parachute （4）What is the authors main purpose of writing the passage?A. To describe the problems of inventing flying vehicles.B. To introduce the latest development of flying vehicles.C. To show the differences between two flying vehicles.D. To advertise the two personalflying vehicles.【答案】（1）D（2）A（3）D（4）A【解析】【分析】本文为说明文，主要讲述一种个人飞行工具很快就会应用于现实。

英语高中阅读理解(人物故事)练习题含解析一、高中英语阅读理解人物故事类1．阅读理解Jon Hoffman was sitting at a red light when he saw a man run out of a store carrying a plastic donation jar full of cash. The Plano, Texas, detective, dressed in plain clothes but wearing his badge (徽章) and gun, caught the man and pinned him to the hood of his car. But Hoffman had trouble containing the thief, and they got into a struggle."The detective has a martial arts background, and he said he thought the suspect must have a martial arts background, too, because he was able to break away so easily," a Plano police spokesperson said.The detective called out for help as a crowd gathered. Among those watching: Andre Harvey and Kirby Sample, two day laborers. Harvey did what has become common these days—he took out his phone and hit record. "I hate to say it, but I thought that this policeman was doing something illegal," Harvey said. "But when he asked for help, I thought, well, there won't be a shooting if I get over there in time.” Harvey jumped into action—while he was still recording the video—as did Sample."Harvey caught hold of the suspect's arms, while Kirby seized his legs, and they were able to get the suspect to the ground to help Detective Hoffman put the handcuffs (手铐) on," said the police spokesperson. The 27-year-old suspect was charged with resisting arrest and other offenses. The charity jar he stole held less than $ 50."I've been on the wrong side of the law several times in my life," Harvey told WFAA. "It feels good to be on the right side and do something positive."After the arrest, the three men got to know each other over steaks and ribs at a local steak house—Hoffman's treat, as a thank-you. But the rescuers say Hoffman deserves credit too. "It could have turned real ugly." Sample told the media "He handled himself like a real professional."（1）What made Hoffman call for help when arresting the suspect?A. He was not on duty.B. He needed witnesses to support him.C. He wanted to push the thief into the car.D. He couldn't control the suspect.（2）Why did Harvey and Kirby record the scene at the beginning?A. To follow the fashion.B. To keep track of the criminal.C. To record the detective's violence.D. To avoid being involved in the incident.（3）What can be inferred about Harvey?A. He was ready to violate the law.B. He might have had some illegal behaviour.C. He was out of work at that time.D. He had a good martial arts background.（4）What is Harvey and Sample's attitude towards Hoffman?A. Appreciative.B. Prejudiced.C. Skeptical.D. Cautious.【答案】（1）D（2）C（3）B（4）A【解析】【分析】本文是一篇记叙文，侦探Jon Hoffman在捉偷善款的小偷时遇到困难寻求帮助，Andre Harvey和 Kirby Sample帮助了他。
高中英语阅读理解练习题(有答案)
一、高中英语阅读理解1．阅读理解Most adults find it hard to recall events from their first few years of life and now scientists have found exactly when these childhood memories fade(消失).A new study has found that most three-year-olds can recall a lot of what happened to them over a year earlier, and these memories persist while they are five and six, but by the time they are over seven, these memories decline(衰退) rapidly.Most children by the age of eight or nine can only recall 35% of their experiences from under the age of three, according to the new findings.The scientists behind the research say this is because at around this age the way we form memories begins to change. They say that before the age of seven children do not have a sense of time and place in their memories. In older children, however, the early events they can recall tend to be more adult-like in the way they are formed. Children also have a far faster rate of forgetting than adults. The findings also help to explain why children can often have clear memories of events but then forget them just a couple of years later.The youngsters first visited the laboratory at the age of three and discussed six unique events from their past, such as family outings, trips to the zoo, and the first day of school. The children then returned for a second session between the ages of five and nine to discuss the same events. The researchers found that between the ages of five and seven, the amount of memories the children could recall remained between 63 -72 percent. However, the amount of information eight-to nine-year-old children could recall dropped to 35 and 36 percent.（1）What does the new study tell us?A.Childhood memories decline with years.B.Three-year-old kids are the cleverest.C.Childhood memories can fade easily.D.Some adults cannot recall past events.（2）What does the underlined word "persist" in Paragraph 2 mean?A.Change.B.Remain.C.Appear.D.Return.（3）What can we learn from Paragraph 4?A.Adults cannot have clear memories of past events.B.Children can think like adults when they get older.C.Children under 7 years old have different ways of forming memories.D.Children often forget things because they have no idea of time or place.（4）In the second session, nine-year-old children _________.A.refused to discuss the same eventsB.remembered all their family outingsC.could recall 72 percent of their past eventsD.only remembered a small part of their past events【答案】（1）A（2）B（3）D（4）D【解析】【分析】本文是一篇说明文，介绍了记忆消失的一些知识。
高中英语阅读理解练习题(有答案)
一、高中英语阅读理解1．（2019•天津）阅读理解How does an ecosystem（生态系统）work? What makes the populations of different species the way they are? Why are there so many flies and so few wolves? To find an answer, scientists have built mathematical models of food webs, noting who eats whom and how much each one eats.With such models, scientists have found out some key principles operating in food webs. Most food webs, for instance, consist of many weak links rather than a few strong ones. When a predator（掠食动物）always eats huge numbers of a single prey（猎物）, the two species are strongly linked; when a predator lives on various species, they are weakly linked. Food webs may be dominated by many weak links because that arrangement is more stable over the long term. If a predator can eat several species, it can survive the extinction（灭绝）of one of them. And if a predator can move on to another species that is easier to find when a prey species becomes rare, the switch allows the original prey to recover. The weak links may thus keep species from driving one another to extinction.Mathematical models have also revealed that food webs may be unstable, where small changes of top predators can lead to big effects throughout entire ecosystems. In the 1960s, scientists proposed that predators at the top of a food web had a surprising amount of control over the size of populations of other species---including species they did not directly attack.And unplanned human activities have proved the idea of top-down control by top predators to be true. In the ocean, we fished for top predators such as cod on an industrial scale, while on land, we killed off large predators such as wolves. These actions have greatly affected the ecological balance.Scientists have built an early-warning system based on mathematical models. Ideally, the system would tell us when to adapt human activities that are pushing an ecosystem toward a breakdown or would even allow us to pull an ecosystem back from the borderline. Prevention is key, scientists says because once ecosystems pass their tipping point（临界点）, it is remarkably difficult for them to return.（1）What have scientists discovered with the help of mathematical models of food webs？A. The living habits of species in food webs.B. The rules governing food webs of the ecosystems.C. The approaches to studying the species in the ecosystems.D. The differences between weak and strong links in food webs.（2）A strong link is found between two species when a predator______.A. has a wide food choiceB. can easily find new preyC. sticks to one prey speciesD. can quickly move to another place（3）What will happen if the populations of top predators in a food web greatly decline？A. The prey species they directly attack will die out.B. The species they indirectly attack will turn into top predators.C. The living environment of other species will remain unchanged.D. The populations of other species will experience unexpected changes.（4）What conclusion can be drawn from the examples in Paragraph 4？A. Uncontrolled human activities greatly upset ecosystems.B. Rapid economic development threatens animal habitats.C. Species of commercial value dominate other species.D. Industrial activities help keep food webs stable.（5）How does an early-warning system help us maintain the ecological balance？A. By getting illegal practices under control.B. By stopping us from killing large predators.C. By bringing the broken-down ecosystems back to normal.D. By signaling the urgent need for taking preventive action.【答案】（1）B（2）C（3）D（4）A（5）D【解析】【分析】本文是一篇说明文，介绍了借助食物网的数学模型，科学家们发现了一些在食物网运营的关键原则。

She is offering $10,000 to any of her friends who can introduce her to her Mr. Right. She wants to find her future husband through this way.The unnamed husband seeker who sent out the email had just finished reading the best-selling book named Lean In. It was 11 p.m. on a Sunday night and she realized this was the second self-help book she had read in the month. She was still single. Things were not looking fine, but there was hope for her still. If the book had taught her anything, it was that she needed to take a more positive role in finding love. After all, if she wanted to get a better job, she wouldn't just sit outside an employer's building and wait for someone to offer it to her, so why should finding a husband be any different? But instead of going out and meeting new people she decided to write an email to all her friends, offering to give them $10,000 on her wedding day if any of them managed to introduce her to her future husband.“I am writing you today because I've decided to make an aggressive action plan on finding the man that I get to hang out with forever,” the woman writes in her email. “Introducing me to my husband is just not high on your to-do list. But I think I have an idea that might change that…” You guessed it, and this is where she offers to reward her “closest friends” with cold hard cash.“I will personally give ten thousand dollars to the friend who introduces me to my husband.”Here is how the program works:Step 1: You set me up on a date with a man.Step 2: I marry that man.Step 3: I give you $10,000 on my wedding day.I know you're thinking that this is nuts.

高三英语阅读理解专项训练100(附答案)含解析一、高中英语阅读理解1．阅读理解When you go to the doctor, you like to come away with a prescription．It makes you feel better to know you will get some medicine. But the doctor knows that medicine is not always needed. Sometimes all a sick person needs is some reassurance that all will be well. In such cases the doctor may prescribe a placebo.A placebo is a sugar pill, a harmless shot, or ail empty capsule. Even though they have no medicine in them, these things seem to make people well. The patient thinks it is medicine and begins to get better. How does this happen?The study of the placebo opens up new knowledge about the way the human body can heal itself. It is as if there was a doctor in each of us. The doctor will heal the body for us if we let it. But it is not yet known just how the placebo works to heal the body. Some people say it works because the human mind fools itself. These people say that if the mind is fooled into thinking it got medicine, then it will act as if it did, and the body will feel better.Placebos do not always work. The success of this treatment seems to rest a lot with the relationship between the patient and the doctor. If the patient has a lot of trust in the doctor and if the doctor really wants to help the patient, then the placebo is more likely to work. So in a way, the doctor is the most powerful placebo of all.A placebo can also have bad effects. If patients expect a bad reaction to medicine, then they will also show a bad reaction to the placebo. This would seem to show that a lot of how you react to medicine is in your mind rather than in your body. Some doctors still think that if the placebo can have bad effects it should never be used. They think there is still not enough known about it. The strange power of the placebo does seem to suggest that the human mind is stronger than we think it is. There are people who say you can heal your body by using your mind. And the interesting thing is that even people who swear this is not possible have been healed by a placebo．（1）What do we know about placebo according to the passage?A. It contains some sort of medicine.B. It won't function if you are negative about medicine.C. People who don't believe placebo can't be healed by it.D. Patients and doctors know clearly how it helps to heal the body.（2）Why is the doctor sometimes the most powerful placebo?A. The patient needs help badly．B. The patient believes in the doctor．C. The doctor knows better about your body．D. The doctor has carefully studied medicine．（3）What does the underlined word “it” in Paragraph 5 refer to?A. The placebo.B. The bad effect.C. The body.D. The medicine.（4）What is the passage mainly about?A. Placebo：Work on Your MindB. Placebo：The Most Powerful MedicineC. Placebo：The Best DoctorD. Placebo：Heal Your Body【答案】（1）A（2）B（3）B（4）A【解析】【分析】本文是一篇说明文，有时候病人的病并不是需要真正的药物来医治，而是需要医生开一些安慰的药剂，安慰病人的心理使病人的情绪得到舒缓，从而有利于病情的痊愈。

Some men had found a yellow metal in the Arctic darkness, and thousands of other men were rushing there. These men wanted dogs that were heavy, with strong muscles for working hard and furry coats to protect them from the cold.Buck lived at a big house in a sunny valley in California which was owned by Judge Miller. He was neither a house dog nor a kennel (狗窝) dog. The whole of Judge Miller's land was his. Buck was king—king over all the crawling, flying things of Judge Miller's lands, humans included.His father, Elmo, had been the Judge's inseparable companion. And when he died, Buck took his father's place. He was not so large—he weighed only sixty kilogram—for his mother, Shep, had been a Scottish sheepdog. Hunting and other outdoor activities had hardened his muscle, and swimming had made himhealthy.This was Buck in the autumn of 1897, when the discovery of gold in the Klondike brought Men from everywhere to the frozen north. But Buck did not read the newspapers. And he did not know that Manuel one of the gardeners helper, was not a good man. Manuel gambled (赌博) and wasted the little money he had. No one saw him and Buck go off on what Buck thought was a walk. No one saw them arrive at the railway station where Manuel sold Buck to a man who was waiting for him.After two days ho was cried off the train in Seattle into a small, high-walled yard. There a fat man in a red sweater broke open the cage with a small axe (斧头)，while holding a club (棍棒) in the other hand. When there was a big enough opening, Buck jumped out like a red-eyed devil, straight at the fat man. But in mid-air, just as his teeth were going to close on the man, he received a shock that he had never felt before. It turned him over and onto the ground. He had never been struck by a club in his life, and he did not understand. He was smashed down a dozen times.Buck saw that he stood no chance against the man with the club. He had learned the lesson, and for the rest of his life he never forgot it. It was his introduction into the world of primitivelaw. In the end a small man called Perrault paid three hundred dollars for him, and he was led away with Curly, a good-natured Newfoundland dog.（1）What kind of dogs did the gold-seekers want?A.Heavy house dogs with yellow hair.B.Strong long-haired dogs.C.Diligent dogs with yellow hairD.Muscular kennel dogs.（2）Buck was proud of himself for the following reasons, EXCEPT that ______.A.he was king over all living things of Judge Miller's landsB.he became the Judge's inseparable companion after his father's deathC.he had a good life with many outdoor activities to get strong and healthyD.he was wanted by gold-seekers thanks to his strong muscles and long hair（3）Which of the following statements is true according to the passage?A.Judge Miller owned a big house and a large piece of land in the Klondike.B.Manuel bought and sold Buck because he needed money to support his life.C.The fat man cruelly beat Buck with a club to teach him how to fight back.D.Buck's introduction into the word of primitive law was obeying the fat man.（4）What can be the suitable title for the excerpt?A.Fall into TroubleB.Fight against a ManC.Escape from TroubleD.Believe in a Man【答案】（1）B（2）D（3）D（4）A【解析】【分析】本文是一篇记叙文，说述了一只名为巴克的狗的遭遇。

高中英语阅读理解专项训练复习题含答案一、高考英语阅读理解专项训练1．阅读理解The negative (负面的) health effects of sleep shortages during the week can't be changed by marathon weekend sleep sessions, according to a new study.Researchers have long known that routine sleep deprivation (缺乏) can cause weight gain and increase other health risks, including diabetes. But there are still some people who hope that shutting off the alarm on Saturday and Sunday will repay the weekly sleep debt and remove any ill effects.The research, published in Current Biology, ruins those hopes. Despite complete freedom to sleep in and nap during a weekend recovery period, participants in a sleep laboratory who were limited to five hours of sleep on weekdays gained nearly three pounds over two weeks and experienced metabolic disruption (代谢紊乱) that would increase their risk for diabetes over the long term. While weekend recovery sleep had some benefits after a single week of inadequate sleep, those gains were wiped out when people returned right to their same sleep schedule the next Monday."If there are benefits of catch-up sleep, they're gone when you go back to your routine. It's very short-lived," said Kenneth Wright, who led the research. "These health effects are long-term. It's kind of like smoking once was — people would smoke and wouldn't see an immediate effect on their health, but people will say now that smoking is not a healthy lifestyle choice. I think sleep is in the early stage of where smoking used to be."Wright said that the study suggests people should prioritize sleep — cutting out the optional "sleep stealers" such as watching television shows or spending time on electronic equipment. Even when people don't have a choice about losing sleep due to child-care responsibilities or job schedules, they should think about prioritizing sleep in the same way they would think about a healthy diet or exercise.（1）What had the researchers already known before doing the new research?A. The actual benefits of weekend recovery sleep.B. Harm to health caused by the lack of routine sleep.C. People's habit of shutting off the alarm during holidays.D. The relationship between body weight and sleep amount.（2）Kenneth Wright mentioned smoking to _________.A. call on smokers to completely abandon smokingB. advise people to go to sleep when they want to smokeC. show people have known the harm brought by smokingD. show people will someday notice the bad effects of sleep deprivation（3）What does the underlined word "prioritize" probably mean?A.Have a low opinion of something.B.Increase the amount of something.C.Cut down something that isn't necessary any more.D.Treat something as being more important than others.（4）What can be the best title for the text?A.Weekend Catch-up Sleep Is a LieB.Bad Sleep Habits Are Harmful to HealthC.A New Study Has an Unexpected DiscoveryD.Advantages and Disadvantages of Catch-up Sleep【答案】（1）B（2）D（3）D（4）A【解析】【分析】本文是一篇说明文，作者通过一项研究与对比举例的方法让大家明白周末马拉松式的“补觉”并不能扭转工作日睡眠不足对健康的负面影响。
